Advanced meter functions
Zero Set Set actual value to reference
AutoHold (on A) Captures and freezes a stable measurement result. Beeps when stable. AutoHold works on the main meter reading, with thresholds of 1 Vpp for AC signals and 100 mV for DC signals.
Fixed decimal point Activated by using attenuation keys

 

Cursor Readout (124B and 125B)
Sources A, B
Single vertical line Average, min and max readout
Average, min, max and time from start of readout (in ROLL mode; instrument in HOLD)
Min, max and time from start of readout (in RECORDER mode; instrument in HOLD)
Harmonics values in POWER QUALITY mode.
Dual vertical lines Peak-peak, time distance and reciprocal time distance readout
Average, min, max and time distance readout (in ROLL mode; instrument in HOLD)
Dual horizontal lines High, low and peak-peak readout
Rise or fall time Transition time, 0%-level and 100%-level readout (manual or auto leveling; auto leveling only 
possible in single channel mode)
Accuracy As oscilloscope accuracy

 

Recorder
The recorder captures meter readings in Meter Recorder mode or continuously captures waveform samples in Scope Recorder mode. The information is stored on internal memory or on optional SD card (with the 125B or 124B).
The results are displayed as Chart recorder display that plots a graph of min and max values of Meter measurements over time or as a waveform recorder display that plots all the captured samples.
